Be One with the Distortions: Adaptive Measurement Templates

Be One with the Distortions: Adaptive Measurement Templates

The Basics

Metrology tasks often require creating a measurement plan on CAD data, which is usually based on provided specifications (like in a drawing) or importing measurements with PMI. The measurement plan can be applied to the actual object in hopes that the fit points will find the right places and geometry elements will be created.

In other words, we often create measurement templates and hope they work.

We can do that right now! Let's create a measurement plan on a crimp connector.

And now the caveat: this method is ideal for when we are dealing with... well, ideal parts, as deviations fall within a reasonable range. When we copy/paste the measurement plan to such ideal parts, fit points will automatically find the right places to land and the right geometry elements will be created. Measuring data is easy in an ideal world.

In a not-so-ideal setting, such as in a heavily distorted part, it's not so simple. Sometimes, there isn't even a surface to land on, and we're left with the highly scientific, metrology-based equivalent of: gibberish. It becomes a hassle to measure distorted parts.

If only we had a better solution...

Introducing adaptive measurement templates!

VG Solution: Adaptive Measurement Templates

Adaptive measurement templates were introduced in version 2022.1 of VGSTUDIO MAX. Just like the mesh compensation module, they calculate and consider deformations compared to the nominal object. (Incidentally, we can use existing mesh compensation results instead!)

Just tick the "adaptive transformation" checkbox in the "transformation" tab and make sure the correct source object is selected when you paste the template to your actual object.

With adaptive measurement templates, fit point creation will take into account the size and direction of distortions and fit geometry elements accordingly, without a hitch… or in this case, without a glitch.

* The part has been heavily distorted for dramatic purposes. If we can make adaptive measurement templates work here, they can work anywhere!
